This work was supported by NSF under DMR-0905842 and the US DOE under DE-AC02-06CH11357.

Metal fluorides that display zero thermal expansion have potential for application in thermally robust IR transparent optical elements. ScF3 displays excellent optical properties, but strong negative thermal expansion. The formation of solid solutions with AlF3 (Sc1-xAlxF3) was explored as a strategy for tuning the properties of ScF3. Extensive solution formation was demonstrated and this provided some control over thermal expansion.  Experiments at elevated pressure and temperature showed that some solid solutions displayed the very unusual characteristic of stiffening on heating.
